Inter-changeability Between Anterior Segment Optical Coherence Tomography and Scheimpflug Imaging in the Evaluation of Corneal Opacity

Purpose To compare the results of corneal evaluation, either total thickness and opacity depth by both technologies AS- OCT Scheimpflug imaging Sirius placido topography. Methods sixty-eight eyes sixty- eight consecutive patients with opacities were examined AS-OCT imaging. Corneal measured compared determining interchangeability using Bland–Altman plotting. Results Total was (470.32±62.10) (463.47±56.47) AS. imaging, respectively (P value = 0.8). While actual measurement opacity, (135.39±119) (85.45±128) Siris P (0.004). Conclusion may be used interchangeably for measuring thickness, while in determination depth. is superior to accuracy boundaries opacity.
